During a hearing in front of the Senate Homeland Security Committee on Wednesday, FBI Director Christopher Wray told senators to 'be careful what you read,' when asked about a recent story involving spy chips from China being secretly embedded into servers owned by Apple, Amazon and other big companies. From a report: Senator Ron Johnson, R-Wis., chairman of the committee, asked Wray when his agency found out about the chips that server manufacturer Super Micro implanted into server hardware, as reported last week by Bloomberg Businessweek. 'I would say to the newspaper article or, I mean, the magazine article, I would say be careful what you read,' Wray replied. 'Especially in this context.' Johnson called on Wray to speak to the accuracy of the story, telling the FBI director that, 'We don't want false information out there.' Wray said he couldn't offer much detail because the agency has a policy of not confirming or denying that an investigation is underway. 'I do want to be careful that my comment not be construed as inferring or implying, I should say, that there is an investigation,' Wray said. 'We take very seriously our obligation to notify victims when they've been targeted.'
